PORTLAND, Ore. — An Oregon man pleaded not guilty Monday to federal charges of aiming a laser pointer at two commercial airliners.

Stephen Francis Bukucs, 39, a private security guard who lives in Portland, aimed the laser pointer at United and JetBlue flights on Oct. 13, according to an indictment unsealed Monday.

He was indicted and arrested last week. Investigators say he’s the first adult to face criminal prosecution for laser attacks in Oregon.
